Resistance training is a vital aspect of your journey to building muscle. Studies have shown that “Resistance training is widely recognized as an effective strategy for promoting skeletal muscle hypertrophy in humans.’’ As a trainer, I always have my clients engage in strength training a few times a week due to the many benefits. However, it can be confusing when it comes down to knowing what free weights you should use.

Dumbbells and barbells are effective free weights for building muscle, but which is better? We will explore the debate on dumbbells vs. barbells and also see which exercises they are best for. This will enable you to make well-guided decisions. It’s time to dive in!

Pros and cons of using dumbbells

One benefit of dumbbells is that they are quicker to change out, allowing smoother workout progression. Also, the best dumbbell exercises, like bicep curls, engage your stabilizer muscles and help to improve balance.

Dumbbells are versatile and flexible, allowing you to target different muscle groups. They are easy for beginners to get used to since they offer a more natural range of movement, closely simulating everyday activities. They will also help you save space, especially in home gyms.

However, dumbbells have downsides. For example, there is no fixed range of motion. This can make people take their joints to extreme limits and risk having injuries. It’s also possible to lose track of your breathing with dumbbells. Consequently, you may experience symptoms like dizziness.

Pros and cons of using barbells

With barbells, you can easily add weight plates to the bar for gradual advancement in resistance training. Since they generally hold more weight, they are effective for heavier lifting.

In addition, barbells are slightly more restricted, so it is easier to maintain proper form and lift heavier weights without frequent adjustments, reducing the risk of injuries.

Barbells are great for complex exercises like deadlifts, bench presses, and hip thrusts, which simultaneously work on many muscle groups and empower faster muscle development.

However, one downside of barbells is that it takes time to load and unload them. This can prolong your workout session. Barbells also do not allow for full-range body movements; they target only one range of motion, which can make your workout feel monotonous.

Are dumbbells or barbells better for building muscle?

Dumbbells offer a wider range of motion and are great for various unilateral and functional exercises that target specific muscle groups and have higher stability needs. Meanwhile, barbells are better for heavy lifting and compound development exercises. They allow you to progressively overload more effectively.

So, essentially, both are good for building muscle. Your overall choice depends on your needs and abilities.

What are the best dumbbell exercises to add to your routine?

Lateral raises

Lateral raises are one of the most effective dumbbell exercises. They specifically engage the lateral deltoids, contributing to more defined, strong, rounded shoulders. You do this by holding a dumbbell on either side of your body and raising them to shoulder level, fully extending your arms.

Bicep curls

Bicep curls target the biceps brachii and help develop arm strength and build well-defined arms. To do the bicep curls, hold the dumbbells with your palm facing forward and bend your elbows, moving the dumbbells up and down.

Overhead tricep extensions

Here, you extend the dumbbell over your head and lower it behind your head. This exercise is great for the triceps, which builds upper arm thickness.

Bent over single-arm rows

This exercise works primarily on the latissimus dorsi, rhomboids, posterior deltoid, and trapezius muscles. To do it properly, hold the dumbbell with your right hand and place your left knee and hand on a bench. Then, bend your elbow to bring the dumbbell up next to your chest before releasing it back down.

Chest flyes

Chest flyes isolate and stretch the pectorals, helping to develop a well-defined chest. To do this, pick up the dumbbells with your palms facing in and lie down on your back. Stretch out your arms to both sides while keeping a slight bend in your elbows before bringing the dumbbells together in front of your chest in a hugging motion.

Which barbell exercises will get you the most gains?

Barbell back squat

The barbell back squat targets the hamstrings, glutes, quads, and core. To perform this exercise, set up the barbell on your upper back and stand with your feet hip-width apart. Bend your knees and push your glutes back as you come down into a squat. Push through your heels to come back to standing.

Bench press

The bench press exercise is a classic for targeting the triceps brachii, pectoralis major, serratus anterior, anterior deltoid, and biceps brachii. Lay flat on a bench, lift the barbell off the rack, and lower it to your chest, bending your elbows. Push the barbell back up until your arms are fully extended before repeating.

Deadlift

A deadlift involves lifting a barbell off the ground. To perform, start with your feet under the bar, bend down, and grip the barbell evenly with both hands. Push through your heels and keep your back straight as you lift the barbell off the floor and come to standing. Deadlifts are a great full-body movement that works on the upper and lower back, trapezius, glutes, core, and hamstrings.

Military press

This exercise primarily targets the anterior, posterior, and medial deltoid muscles. You do it by placing the barbell on a rack with your desired weight at shoulder height. Stand behind the barbell and grab it with both hands slightly wider than your shoulder width, then lift it above your head. Bring it back down below chin level and repeat the movement.

Barbell hip thrust

Barbell hip thrusts primarily target the glutes and hamstrings. To do the exercise, sit down with your feet flat on the floor and your knees bent, and put your upper back up against a flat bench. Place the barbell across your hips, grab it with both hands for support, and push through your heels to bring your hips up toward the ceiling, lifting the weight. When your knees form a 90-degree angle, pause for a moment before bringing the weight back down.

Get the “Extraction” body before Chris Hemsworth’s threequel
Extraction Workout

Movies lied to me when I was a kid. When I joined the Army, I had dreams of being an Army Ranger. Too many movies made me think I could be a special operator and maybe even get myself a great nickname like the GI Joes. Instead, I told one of the sergeants of my aspirations, and he flat out said I wouldn’t make it. Not that I couldn’t do it, but that they wouldn’t let me. I was too big. 6’5″ and 220 pounds was going to require too many calories. You see, Arnold Schwarzenegger, Sylvester Stallone, and Dwayne Johnson made me think that the elite soldiers needed to be hulking giants. Or world-class martial artists like Bruce Lee, Chuck Norris, or Jean-Claude Van Damme. And since I couldn’t do a roundhouse, I decided to follow the more practical path of the everyman like Bruce Willis, Nic Cage, and Tom Cruise.

You see, special operators need to be agile. They need mobility. That is why Chris Hemsworth adopted a workout with that goal to prepare for his third turn as Tyler Rake in his new Netflix film, Extraction 3.

Ditching the boring golf gear: Travis Mathew and Liberty London collaborate to bring personality to the course
Chair, Furniture, Person

I remember watching golf when I was a kid; everyone, and I mean everyone, looked the same. There are rules on a golf course. A collared shirt, no denim, a very specific look is what they go for. It is tradition, and tradition is hard to argue with. Then came Tiger Woods and John Daly. Tiger found a way to make this boring tradition a uniform. You could see the red Nike polo and black pants and knew exactly who it was. Daly? Well, he went the other way and patterns became a wild calling card. Travis Mathew and Liberty London found a way to mix both of these concepts to bring a bold new look to the game of golf.

What makes this collaboration particularly exciting is seeing Liberty’s heritage designs and colour language brought into the world of golf in such a fresh way. The striking print combinations, considered handfeel, and balance of high-performance golfwear with relaxed lifestyle pieces create a collaboration that feels both unexpected and distinctly Liberty. – Pere Bruach, Design Manager at Liberty London
